Technical Specifications

• Dimensions: 124×88×0.5 mm
• Materials: Galvanized steel sheet housing, aluminum blades, stainless steel shaft and spring

Installation

The duct damper should preferably be installed horizontally, fully inserted into the duct. It can also be installed vertically. For flexible hoses, hose clamps are necessary to secure the check valve.

Use

The valve blades only open in the direction of outgoing air, ensuring efficient and quiet operation thanks to a foam rubber seal that reduces noise and provides an additional airtight seal.
